I do alot of remolding in residential settings. That said I have my fair share of commercial accounts. If I were you I would painstakingly work up every run I could think of that would be required. As you know your costs for residential runs. You will need to find your costs for your commercial.
Keep in mind things like being on site when the masons installing block to get the conduit in or the pvc conduits that will go into the floor before the pours etc. Is this design build? I would also make it known that you are a for profit business and that freebees will not be part of the deal. Lastly you must know your conduit abilities it is not something to jump in and learn on a job like this.
Good luck~!
